Rehersal is a testing framework for Scala. It replaces the built-in SUnit functionality.
The project uses Expectations rather than Assertions, with real boolean operators. Tests can have any name, with any punctuation.
Main features:
- A very simple, novel testing API: Test names can have spaces and real punctuation!
- Use of Expectations: Instead of assertions, which are tedious to extend, Rehersal uses Expectations.
- No Attributes! No Funny Method Names! Tests can have any name, and normal punctuation, enabling "Tests as Documentation" much more naturally.
- Can be used on the command line: Quick and easy!
- Can be used simply with a straightforward ant task Just taskdef and go
- Class Loader safe: Tests are loaded in a separate class loader, allowing garbage collection and safe destruction!
- Test Categories: Tests are categorized to allow the mixing of unit, integration, regression, etc tests in the same project...

Blue for CSound project is a java program for use with Csound. Its interface is much like a digital multitrack, but differs in that there timelines within timelines (polyObjects). This allows for a compositional organization in time that seems to me to be very intuitive, informative, and flexible.
Main features:
- SoundObjects are the building blocks within blues score timeline. soundObjects can be lists of notes, algorithmic generators, python script code, csound instrument definitions, and whatever plugins that are developed for blue. these soundObjects may be text based, but they can be completely GUI based as well.
- Timeline allows for visual organization of soundObjects
- Polyobject are objects which hold other soundObjects, and have timelines in themselves. working within them on their timelines and outside of them on the parent timeline help organize and understand the concepts of objective time and relative time between different objects
- The soundOject library allow for instantiating multiple copies of a soundobject, which allows for editting the original object and updating all copies
- noteProcessors allow for modifying the soundObjects properties, i.e. adding 2 to all p4 values, multiplying all p5 values by 6, etc.
- The orchestra manager organizes csound instruments and functions as an instrument librarian. you can selectively choose what instruments to output to the generated csound .csd file, so you can feel free to keep all of your instruments in a large library and output only the ones you need, cutting down on load time for csound.
- Syntax hilighting of csound language
- Use of scripting for user extensibility
- SoundObject freezing - free up CPU cycles by pre-rendering objects
- Microtonal PianoRoll allows editing notes using any Scala scale
- blueLive - work with soundObjects in realtime to experiment with musical ideas or performance
- and more!
